REMOVABLE GRATE FOR COOKING STOVES, 850.

SPECIFICATION forming part of Letters Patent No. 634,867, dated 'oetober17, 1899.

Application filed April 6, 1898.

T0 aZZ whom, it may concern: I

Be it known that I, ARTHUR K. BEoKwITn, a citizen of theUnited States,residing at the city of Dowagiao, in the county of Cass and State ofMichigan, have invented a certain new and useful Removable Grate forCook- Stoves, &c., of which the following is a specification. v

This invention relates to improvements in grates for stoves or ranges.

IIeretofore the usual method of inserting grates into cook-stoves andranges has been by securing the grates in a frame supported in suitableways in the body of the stove. hen it is desired to remove the grates inthat construction, it is necessary to slide the frame from the stove,which is usually a matter of considerable difficulty, owing to the factthat the frame or grate has become more or less warped with the heat.

The objects of this invention are to provide an improved construction ofgrate which can be readily removed from the stove without the necessityof withdrawing the grateframe.

A further object, also, is to provide a grate which can be easilychanged from a woodgrate to a coal-grate.

Further minor objects will definitely ap pear in the detail descriptionto follow.

I accomplish these objects of my invention by the devices and meansdescribed in this specification.

The invention is definitely pointed out in the claims.

The structure is fully illustrated in the accompanying drawings, forminga part of this specification, in which- Figure l is a verticaltransverse detail sec tional view through the firebox of a cookstove ofthe usual pattern, taken on a line corresponding to line 1 l of Fig. 2,showing my improved grate-bars in position. is a top plan view of thegrate-frame and grate-bars according to my invention and the grate beingset as a coal-grate. Fig. 3 is a top plan view of the same construction,with the grates shifted to form a wood-grate. Fig. 4: is an endelevation of the structures appearing in Figs. 2 and 3, taken from theright-hand side. Fig. 5 is a sectional view Fig. 2

taken on a line corresponding to line 5 5 of Figs. 2 and 3. Fig. (i isan end elevation of the grate, taken from the left-hand end of" Figs. 2and 3. y

In the drawings similar letters of reference refer to similar partsthroughout the several views, and all of the sectionalviews are takenlooking in the direction of the little arrows at the ends of thesection-lines.

Referring to the lettered parts of thedrau lugs, A is the stove-body.

B is the grate-frame, and A A are the stove-linings, which rest upon andare supported by the grate-frame.

My improved grate-frame has loops G G to the inner end to receivejournals E on the ends of the grate-bars. Hooks F F, corresponding tothe loops Gr G on the rear and opening toward the center of thegrate-frame B, are provided on the front end of the grateframe 13 andare to receive the front ends or journals of the grate-bars. The frontends of the grate-bars are made square to receive pinions D D, which aresupported on the same so as to be easily removed. The said pinions areretained on the shafts E E by suitable cotter-pins a a. The ends of theshafts project beyond the pinions to receive the crank or shaker for thepurpose of shaking the grates. A suitable stop is provided for thegrate-bars. The pinions D are of such size that they mesh when placed onthe shafts E E at the end of the grate-bar and so hold thejournals ofthe shafts E E securely in place in the hook portions F.

Then it is desired to remove this grate from the stove, it isunnecessary to remove the grate-frame. It is only required to with drawone of the cotter-pins a, remove the pinion, when the bar can be easilyswung out of the hook-bearin g F and then withdrawn from the loop G atthe opposite end. When. one grate-bar is removed, the other bar can beremoved without detaching the pinion by the same motion. Thus it is veryeasy to remove and renew the grate-bars from the grate* frame.

I have provided my improved grate-bars with double grate-surfaces. Theconvex side of one of the grate-bars O, I prefer to make solid, havinggrate-openin gs only through the concave wing of the same.

- one of the pinions D removable.

The other bar of the pair is made with openings through both the concaveand convex wings. Thus it will be observed that by placing the grate inthe position indicated in Figs. 1 and 2 the whole of the opening is leftfree, but by rotating the grate to the position indicated in Fig. 3one-half of the air-opening is cut off, making the grate better adaptedfor use in a woodstove. The advantages of this will be readilyunderstood. I desire to state in this connection that the particularformation of grates is not essential to my improved means of securinggrate-bars in position, as I have inclicated which could be used withother means of support.

I will state that to make the device successful and operative it is onlynecessary to make However, the bar can be constructed more readilyindependent from the pinion, and therefore as the pinions do not receivewear and are not materially effected by the heat of the stove it isdesirable to make the pinions removable, so that it will not benecessary to renew them in renewing one or more of the grate-bars.

YVith this method of supporting the grate bars it will also be readilyunderstood that it is unnecessary to have the grate-plate adapted toslide into and out of said body, which under certain circumstances mightbe'of considerable value in .the manufacturing of stoves. It is alsoneedless to remark that in securing the pinions on the shafts of thegrate-bars so long as they are conveniently retained in position it isimmaterial how the same is accomplished if one pinion is made easilyremovable.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, 13- v 1. The combination of a grate-platehaving loops 0, C, at one end and hooks F, F, at the opposite end andopening toward the center; grate-bars having suitable journals at eachend supported in loops G, G, and bearings F, F, the ends of the shaftsbeing squared, and

gears on the ends of the shafts of the gratebars of such size as to meshwith each other when the journals of the grate-bars are in position inthe hooks, all coacting substantially as described for the purposespecified.

2. In a rocking grate, gratebars journaled at each end; journal-hearingsin the stove for each end, the bearings at one end of the bars beinghook-shaped and opening toward each other; pinions on said grate-barsone at least of which is removable adapted to mesh with each other, whenthe journals of the gratebars are in position in the hooks, and retainthe bars in position and facilitate their easy removal for the purposespecified.

In witness whereof I have hereunto set my hand and seal in the presenceof two witnesses.
